🔍 Key Concepts

• Thermal expansion of liquefied gases (like CO₂) in fire systems • Relationship between cylinder pressure and ambient temperature for CO₂ • Why safety (burst) discs must protect the cylinder before dangerously high temperatures

💭 Think About

• Think about the normal storage pressure of a CO₂ cylinder at room temperature and how much the temperature must rise to almost double that pressure. • Consider which listed temperature would more likely be associated with a serious overheating or fire-exposure condition rather than normal warm weather. • Ask yourself: would safety discs be designed to rupture at a temperature commonly found in machinery spaces, or at a temperature reached only in abnormal, high-heat situations?

✅ Before You Answer

• Check typical CO₂ cylinder pressure at about 70°F and compare that to 2,700 psi in relative terms (e.g., is it much higher or only slightly higher?). • Consider what approximate ambient temperature range is expected in normal service versus emergency (fire) conditions in an enclosed space. • Verify that the chosen temperature reflects a clearly abnormal, high-heat condition, appropriate for a safety device that should not operate in normal service.
